When defining a ClusterIP Service, we can specify externalIP, and the
traffic policy of externalIP is subject to externalTrafficPolicy.
However, the policy can't be set when type is not NodePort or
LoadBalancer, and will default to Cluster when kube-proxy processes the
Service.
This commit updates the defaulting and validation of Service to allow
specifying ExternalTrafficPolicy for ClusterIP Services with
ExternalIPs.

PVC and containers shared the same ResourceRequirements struct to define their
API. When resource claims were added, that struct got extended, which
accidentally also changed the PVC API. To avoid such a mistake from happening
again, PVC now uses its own VolumeResourceRequirements struct.
The `Claims` field gets removed because risk of breaking someone is low:
theoretically, YAML files which have a claims field for volumes now
get rejected when validating against the OpenAPI. Such files
have never made sense and should be fixed.
Code that uses the struct definitions needs to be updated.
The fact that the .status.loadBalancer field can be set while .spec.type
is not "LoadBalancer" is a flub. Any spec update will already clear
.status.ingress, so it's hard to really rely on this. After this
change, updates which try to set this combination will fail validation.
Existing cases of this will not be broken. Any spec/metadata update
will clear it (no error) and this is the only stanza of status.
New gate "AllowServiceLBStatusOnNonLB" is off by default, but can be
enabled if this change actually breaks someone, which seems exceeedingly
unlikely.
PDB with an empty selector `{}` is selecting all the pods in a namespace.
But, during the `drain`, all the pods are getting evicted which is not expected.
This change should fix the issue and honor the pdb before evicting the pods.

Instead of numerating all the etcd endpoints known by apiserver, we will
group them by purpose. `etcd-0` will be the default etcd, `etcd-1` will
be the first resource override, `etcd-2` will be the second override and
so on.
These don't belong in pkg/proxy/util; they involve a completely
unrelated definition of proxying.
Since each is only used from one place, just inline them at the
callers.
The ipallocator for the new IPAddress object use the golang big.Int
library for some math operations, like adding an offset to an IP
address.
We use the bytes array to convert between big.Int and IP addresses,
however, IP addresses are always represented as 4 or 16 bytes arrays.
Big int bytes representations just return the byte array until the
most representative number, this requires that we need to prepend
these extra bytes for IPs with leading zeros.

This touches cases where FromInt() is used on numeric constants, or
values which are already int32s, or int variables which are defined
close by and can be changed to int32s with little impact.

add a new ClusterIP allocator that uses the new IPAddress API resource
and an informer as the backend, instead a bitmap snapshotted on etcd.
